Answer 1

First of all, The error you posted shows "GET" error not "POST".

Now the question how to solve it. The compiler only detects code related issues in your application.

If you are making request to specific URL and your code implementation is correct then compiler will show no errors.

But when application runs then actually that API call is being initiated. In your case, Your application is not able to locate URL " http://127.0.0.1/traceur ", So make sure backend is working properly and application gets some data hitting that API.
